Application of dynamic vibration absorber for vertical vibration
A variable mass tuned particle absorber is designed for the nonlinear vertical vibration control of the corrugated rolling mill in the composite plate rolling process. Considering the nonlinear damping and nonlinear stiffness between the corrugated interface, a three-degree-of-freedom nonlinear vertical vibration mathematical model of corrugated Rolling mill vibration is a worldwide problem, although it has been found that the mill structure defects are the main cause of vibration, but the inhibition measures are difficult to implement. When the roller has vertical vibration, periodic change of contact arc length will cause rolling force fluctuation. While the main drive system hasRolling process and its influence analysis on hot continuous

Review on vertical roller mill in cement industry & its
Vertical roller mill has proved to be a popular choice for finished cement grinding over all other machineries due to advantages like low power consumption, higher capacity, process simplifications and compactness but it is also very sensitive to vibrations and can deteriorate productivity if process optimization is varied slightly.The operation of the world’s first multimode continuous casting and rolling F3 (3rd finishing mill stand) finishing mill was hampered by frequent vibrations. Mill vibrations were found to be caused by the transmission and coupling of vibration energy flow. In this study, an overall finite element model of the F3 stand is established based on the Vibration Energy Coupling Behavior of Rolling Mills under
